The tent comprises a [52] U.S.Cl.....

canopy for receiving at least the head of a patient being medi cally treated. The canopy has a plurality of areas correspond- A6lm ing to the locations to which the conduits from the plurality of machine units extend. The areas are selectively removable from the canopy to enable the canopy to be used with any one of the plurality of machine units.

The principal object of the present invention is the provision of a new and improved tent construction which may be used with any one of a plurality of machine units, even though the machine units have conduits extending therefrom to differentlocations, thereby reducing the need for different tent constructions for use with each different machine unit.

A further object of the present invention is the provision of a new and improved oxygen tent which is constructed as to be capable of use with any one of a plurality ofdifferent machine units having conduits which may be of different diameters and located in different locations, thereby enabling a hospital using the various machine units to reduce the number of different types oftents which must be maintained.

A still further object of the present invention is the provision of a new and improved oxygen tent which is capable of use with any oneof a plurality if machine units which have conduits affixed thereto and extending to a predetermined location therefrom and through which conduits a controlled atmosphere is directed into the tent, and wherein the tent comprises a canopy for receiving at least the head of a patient to be medically treated and wherein the canopy has a plurality of removable areas which may be selectively removed from the canopy to enable the canopy to be used with any one of the machine units.

A further object of the present invention is the provision of a new and improved tent, as noted hereinabove, wherein the areas of the canopy which are selectively removed are defined by a tear line providing for ready removal of the area for purposes of use with any given machine unit.

Further objects and advantages of the present invention will be apparent to those skilled in the art to which it relates from the following detailed description of a preferred embodiment thereof made with reference to the accompanying drawingforming a part of this specification and in which:

FIG. 1 illustrates a tent embodying the present invention;

FlG. 2 is a side elevational view of the tent shown in FIG 1',

and

FIG. 3 is a fragmentary sectional view, taken approximately along the line 3-3 of FIG. 2.

The present invention provides a new and improved tent for use in the treatment of a patient and which comprises a canopy for receiving at least the head of a patient to be medically treated. The tent of the present invention is capable of use with any one of a plurality of machine units which have conduits affixed thereto and extending to a predetermined location therefrom' and through which conduits a controlled at' mosphere is directed into the tent. in view of the fact that the tent of the present construction is capable of use with any one of a plurality of machine units. a hospital utilizing the tent of the present construction need not maintain separate invcnto ries of tents for each and every type of machine unit which it may have. This, of course, greatly reduces the problems of administration and inventories for the hospital.

A preferred embodiment of the present invention comprises a tent 10, illustrated in FIG. 1 in association with a machine unit ll. The tent 10, of course, comprises a canopy which receives at least the head of a patient located on a hospital bed. The canopy is supported in any conventional manner by a frame a located adjacent the bed. The patient is being medically treated and the head of the patient is located within a controlled atmosphere within the canopy, which atmosphere is controlled and maintained by the machine unit I]. The canopy l0, ofcourse, can be of any suitable size and may encompass the entire patient.

As noted abovc, the machine unit 1] creates and maintains a controlled atmosphere within the tent 10. The machine unit ll includes a pair of conduits l2, 13 which are fixed at one of their ends, l4, 15, respectively, to the machineunit H and which extend to a predetermined location from the machine unit ll. A controlled atmosphere is directed into the tent through one of the conduits l2, l3 and is recirculated back to the machine unit ll through the other of the conduits 12, 13. The conduits l2, 13 may have a flexible portion intermediate their ends to allow for some small adjustment of the location of the outboard end of the conduits. The machine units of the type designated 11 are well known in the art and it is not believed necessary that they be described in detail.

There are a plurality of machine units, such as the one designated 11, all of which may be utilized in controlling the atmosphere in the canopy 10'. The various machine units which are available also have conduits which are connected with the respective machine unit and which extend therefrom to a predetermined location. However, the conduitsof the various machine units do not extend uniformly to the same predeterminedlocation. and therefore it is necessary to provide canopies with openings in different locations for use'with the different types of equipment,such as that designated H.

The canopy l0 of the present invention is constructed so as to be capable of use with any of a plurality of machine units, even though the outboard ends of the conduits of the machine units may be disposed in different locations. To this end, the canopy 10 has a machine end 20 which is provided with a plurality of areas which are designated AA. BB. CC and DD. These areas, as should be apparent front FIG. 2. are of different diameters and located differently on the machine end 20 of the canopy 10. These respective areas are located at the predetermined location of the outlet ends of conduits for different machine units, such as the machine unit ll.

These areas AA, BB, CC and DD are selectively removable from the machine end 20 of the canopy 10 so that the canopy may be used with any one of the machine units having conduits with their outboard ends corresponding with the areas removed from'the machine end 20 of the canopy 10.

As illustrated in FIG. 1, the areas AA have been removed from the canopy to provide openings 21, 22 which cooperate with the conduits 12, 13, respectively, for providing the controlled atmosphere within the canopy. It should be clear from the above that another machine unit having conduits which extend to location BB could be used with the canopy by removing area BB from the machine end of the canopy. This is true also for machine units haying conduits extending to a location corresponding with the area CC or DD.

It may also be desireable on occasion to connectto the canopy a machine unit having only one conduit and the area E is provided for this purpose. It should also be apparent that more than one machine unit may be used at the same time with the canopy [0, if such ever becomes desirable.

In the preferred embodiment of the present invention, the areas AA,-BB, CC, DD and E which are removable from.the

canopy l0 are formed on the panel 30 which is secured to the man body of the tent 10. The tent 10, as shown in FIGS. 2 and 3, is provided with an opening 31 over which the panel 30 is secured. The panel 30 is a plastic member, and the main body of the tent 10 is likewise plastic. The panel 30 is heat sealed in the area designated 32, around the edges thereof to secure the panel 30 to the main body of the canopy l0 and in a sealed relation around the opening 31. At the same time, the areas designated A are defining the various areas. The panel 30 can be formed and heat sealed onto the tent 10 in one operation. or the weakened areas 33 may be formed in the panel 30 in a separate operation and the panel heat sealed to the canopy 10 in another operation.

The areas AA, BB, CC, DD an E may be selectively removed by grasping the area and tearing it away from the panel 30. The areas readily tear from the panel 30 to form the openings in the canopy for receiving the conduits of the corresponding machinc units. The areas may be appropriately coded for thevari'ous machine units so that the proper areas would be removed corresponding to the machine unit.

While a preferred embodiment of the present invention has been described hercinahove in considerable detail, certain modifications. changes and adaptations may be made therein, and it is intended to cover all such changes, modifications and adaptations which come within the scope of the appended claims.
